HARVESTER.

SPEGIFICATION fOrming part of Letters Patent No. 754,926, d t d M h 15,1904,

Original application filed June 11, 1903, Serial No. 159,702. Dividedand this application filed December 11, 1908. Serial and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to harvesters; and its object is to improve themechanism for receiving and delivering the cut grain or grass, so thatthe freshly-cut grain will be prevented from falling onto the platformwhile that comprising the sheaf last out is being delivered.

In order to render the invention easily understood, reference is had tothe accompanying drawings, in which like reference-numerals indicatesimilar parts throughout.

In the drawings, Figure 1 represents in side elevation my invention asapplied to a harvester. Fig. 2 is a sectional elevation on the line A BC of Fig. 1, and Fig. 3 is adetail of certain adjusting means.

Referring to the drawings, the axle 1 of the main driving-wheels 2imparts its motion by means of the chain-wheel 3 and the chain 4 to achain-wheel 5, carried upon one-half of a clutch mechanism 6 and 7,fixed upon a hollow sleeve 8, arranged to rotate loosely upon astationary shaft 9. This shaft 9 is carried by a frame 10, which isfixed to the body of the machine. The sleeve 8 carries two spacedstar-wheels 11, having preferably four rays or arms. Three transverseblades 12 for feeding the uncut grain to the knives are mounted upontwo-part arms 13, the members of which arms are slidably mounted oneupon the other, the inner members 14 being fixed to the rays of thestar-wheel. Upon the end of the stationary shaft 9 is mounted a crank15, to which the movable parts 13 of the arms are connected by means oflinks or rods 16, by means of which the transverse blades are given areciprocatingmovement to and from the axis of the reel. The fourth rayof the star-wheel (No model.)

carries a fixed arm 17, to the outer end of which is pivoted, at 18, arake 19, which serves to deliver or discharge the cut grain from theplatform 20. Another arm, 21, is

pivoted to a projection of the star-wheel at 22 with a lateralprojection 26 from the rake 19.

For the purpose of tilting the grain-platform 20 a segmental guide-plate27 is mounted upon the frame of the machine concentric to the axis ofthe reel. Within the guideplate is adapted to travel a roll 28,connected, by means of a rod 29, with the platform. A lateral arm 30',carried by the star-wheel, enters the guide 27 upon each revolution ofthe reel and pushes the roll 28 from its position at 28 into the recessat the top of the guideplate, effecting in this way a raising of therack from the position shown in dotted lines to that shown in full linesin Fig. 1.'- Upon the further revolution of the reel another arm, 31,passes through the guide-plate and trips the lever 32, which dischargesthe roll 28 from the recess and causes the sameto fall by gravity to theposition shown in dotted lines, thus lowering the platform. It will thusbe seen that the platform is raised and lowered at each revolution ofthe reel.

' A relative movement is imparted to the rake 19 and the transverse bar23 in the following manner: i

A straight guide 33 is mounted on the frame 10 or the segmentalguide-plate 27, and aroll 34 is carried by the arm 21. the guide 33andthe roll 34 to each other is such that as the reel revolves the rollcontacts with the guide, and the forward movement of the arm 21 isthereby temporarily retarded, while the fixed arm 17 carrying the rake19, continues its onward movement. The retarding of the arm 21 and thetransverse bar 23 constitutes of said bar 23 a barrier to temporarilyprevent the freshly-cut grain from falling upon the platform 20. At thesame The relation of 7 time the onward movement of the arm 17 causes thelateral projection 24 to transmit, by means of the rod 25' and theprojection 26, a sudden backward movement to the fingers of the rake 19against the tension of the spring 35. The further progression of thereel causes the roll 34 to assume a position in which it can pass theguide-plate 33, and the obstacle being removed the spring 35 causes therake 19 to spring suddenly forward, discharging the grain from the rackor platform 20, which is at this time dropped to the position shown indotted lines.

In order to effect an adjustment whereby the blades 12 will feed thestanding grain to the knives at a time corresponding to the nature ofthe ground, the height of the grain; &c. a segmental arm 86 is bolted tothe frame and provided with a number of apertures, in which may beadjusted a lever 37, fixed upon the end of the shaft 9, whereby theshaft may be partially rotated and the point of maximum throw of thearms be varied.

Having thus fully described my invention, what I claim as new, anddesire to secure by v Letters Patent, is--- 1. In a harvester, thecombination, with a grain-platform, and a rotary reel, of a rakepivotally mounted on the reel and serving to discharge the cut grainfrom the platform, an arm pivotally mounted on the reel, a transversebar carried by the arm, a connection between the arm and the rake, andmeans for retarding the motion of the arm, whereby the rake willdischarge the grain from the platform and the transverse bar will serveto prevent the deposit of freshly-cut grain during such discharge;

2. In a harvester, the combination, with a grain-platform, and a rotaryreel, of a rake pivotally mounted on the reel and serving to dischargethe cut grain from the platform, an arm pivotally mounted on the reel, atransverse bar carried by the arm and occupyinga position immediatelybehind the rake, a connection between the arm and the rake, and

means for retarding the motion of the arm, whereby the rake willdischarge the grain from the platform and the transverse bar will serveto prevent the deposit of freshly-cut grain during such discharge.

3. In a harvester, the combination, with a grain-platform, and a rotaryreel, of a rake pivotally mounted on the reel and serving to dischargethe cut grain from the platform, an

arm pivotally mounted on the reel, a transverse bar will serve toprevent the deposit of freshly-cut grain during such discharge.

L. In a harvester, the combination, with a grain-platform, and a rotaryreel, of a rake pivotally mounted on the reel and serving to dischargethe cut grain from the platform, an arm pivotally mounted on the reel, atransverse bar carried by the arm, a connection between the arm and therake, a guide mounted on a fixed portion of the apparatus, and a rollcarried by the arm whereby the guide will contact with the roll as thereel rotates and temporarily retard the movement of the arm and its bar,causing, at the same time, a movement of the rake independent of thereel, facilitating the discharge of the grain from the platform andpreventing the deposit of freshly-cut grain during such discharge.

5. In a harvester, the combination, with a grain-platform, and means forperiodically raising and lowering the same, of a rotary reel, a rakepivotally mounted on the reel and serving to discharge the cut grainfrom the platform, an arm pivotally mounted on the reel, a transversebar carried by the arm, a connection between the arm and the rake, andmeans for retarding the motion of the arm, whereby the rake willdischarge the grain from the platform and the transverse bar will serveto prevent the deposit of freshly-cut grain during such discharge.

6. In a harvester, the combination, with a grain-platform, a reel, asegmental guideplate, a roll traveling in the guide and a connectionbetween the roll and the platform, of a rake pivotally mounted on thereel, an arm pivotally mounted on the reel, a transverse bar carried bythe arm immediately behind the rake, a connection between the arm andthe rake, means carried by the reel for releasing the roll and allowingthe platform to drop, of means operating simultaneously to retard theonward movement of the arm, whereby the rake will discharge the cutgrain from the lowered platform and the transverse bar will prevent thedeposit of freshly-cut grain during such discharge.

7 Ina harvester, the combination, with a grain-platform, a reel, asegmental guideplate, a roll traveling in the guide, an arm carried bythe reel andoperating to push the roll upward in the guide, a recess forthe retention of the roll in its uppermost position, a lever pivotednear the recess, a second arm carried by the reel and operating tocontact with the lever and expel the roll from the recess, and aconnection between the roll and the platform whereby the platform willbe periodically raised and lowered as the reel rotates, of a rakepivotally mounted on the reel, an arm pivotally mounted on the reel, atransverse bar carried by the arm and occupying a position immediatelyfollowing the rake, a stationary guide-plate, and a roll carried by thearm in such-position as to contact with the guide-plate at the momentthe roll is expelled this specification inthe presence of two Witfromthe recess, whereby the rake will bedacnesses. tuated in such manner asto facilitate the ischarge of the grain from the platform and the VBERNARD HOLTHAUS' 5 bar Will temporarily prevent the deposit ofWitnesses: freshly-cut grain during such discharge.
